Instead, they modified the DNA in the chloroplasts-organelles responsible for photosynthesis, not reproduction.

相反，他们修改了体中的DNA，体是负责光合作用而不是繁殖的细胞。

Over time, that evolved into a chloroplast, the organelle that does photosynthesis.

随着时间的推移，它们进化成体，也就是进行光合作用的细胞。

Today, every single plant has cells like this, full of chloroplasts and mitochondria.

今天，每一株植物都有这样的细胞，充满体和线粒体。

Chloroplasts are found only in plant cells and contain chlorophyll.

体仅存在于植物细胞，而且含有。

It does so using a chloroplast-like organelle, like the one plants use to capture sunlight.

它是利用一种类似于细胞的体达成这一目的，就像植物捕捉阳光一样。

Plant cells also contain chloroplasts which are filled with a chemical called chlorophyll.

植物细胞还包含体，里面充满了一种叫做的化学物质。

It sucks the cell empty and digests most of its contents, but the chloroplasts remain intact.

它将细胞吸空，并消耗其大部分物质，留下“体”完好无损。

Finally, let's look at the chloroplast.

最后是体。

Simple plant cells may have only one or two chloroplasts in them.

简单的植物细胞可能仅有一个或两个体。

You won't find chloroplasts in animals — they're more of a plant thing. You wouldn't understand, Blobfish.

你在动物身上找不到体——它们更像是植物的组成部分。你不会明白的，水滴鱼。

This makes the chloroplasts able to sustain themselves for longer inside the slug.

这使得体能够在鼻涕虫体维持更长时间。

As incredible as this adaptation is, there are more than 70 species of slug that steal chloroplasts from their food.

如此令人难以置信的适应性，竟然有多达 70 多种鼻涕虫从食物中窃取体。

And cyanobacteria became chloroplasts, the organelles that carry out photosynthesis today.

蓝藻变成了体，即今天进行光合作用的细胞。

Tripos is in turn eaten by other mixotrophic algae, providing frequent opportunity for exchange of organelles such as chloroplasts.

角藻又被其他混合营养藻类吞食，为体等细胞的交换提供频繁的机会。

We call this kleptoplasty." Klepto" , as in to steal, " plasty" as in chloroplast, right?

我们称这种 kleptoplasty 为“Klepto”，就像偷窃一样，“plasty”就像在体中一样，对吧？

Taking a chloroplast and sticking inside of a cellis not enough to become photosynthetic.

获取体并粘在细胞部不足以进行光合作用。

But these first eukaryotic plants were soon consumed by other animals, which hijacked the precious chloroplast, just like Elysia.

但这些最早的真核植物很快就被其他动物吃掉了，并被劫持了珍贵的体，就像海天牛一样。

Some of these tiny plants were not digested and lived on in the animal cells, eventually giving rise to chloroplasts.

这些微小植物并无法消化和吸收这些动物细胞，最终形成了体。

And at the end of these branches, we have these cul de sacs that are loaded with chloroplasts.

在这些分支的尽头，我们有这些装有体的死胡同。

Chloroplasts need things that the algae provide to themthat animals shouldn't be able to do.

体需要藻类为它们提供的动物无法提供的东西。
